I can only tell you what I would try. Hot baths or showers, a hort walk a couple times a day. I also have this thing where I put my feet again the edge of a door and hang on the handle on both sides and lean back and stretch toward my feet with my head,thereby stretching my back and neck. I would also try and see my primary care doctor and ask for whatever help they can give me. Quitting is really stinking hard! Take all the help you can get.
